Problems solved by technology

In order to manufacture composite materials of carbon materials and aluminum, the following problems need to be solved: one example is: carbon materials, such as carbon nanomaterials, are difficult to disperse due to the interaction of van der Waals forces between materials , making it difficult to disperse uniformly in aluminum
In addition, between carbon materials and aluminum, it is difficult to mix carbon materials and aluminum due to the difference in surface tension

Abstract

Disclosed is a method for producing planar carbon nanoparticles. In order to produce planar carbon nanoparticles, first, a graphite material and balls for ball milling can be fed into a milling container, wherein the ball milling container is arranged in a disk rotatably in a second direction, and the disk is rotatable towards a first direction reverse with the second direction. Subsequently, the disk and the ball milling container are rotated at the predetermined time, so that the balls for ball milling is contacted with the wall surface of the ball milling container in a friction manner, and accordingly the balls for ball millng are driven to rotate,and a mechanical shearing force is applied to the graphite material. Then, planar carbon nanoparticles produced from the graphite material can be separated. According to the above-described method for producing planar carbon nanoparticles, planar carbon nanoparticles may be mass-produced in a short amount of time using a relatively simple process.

technical field [0001] The present invention relates to a method for manufacturing plate-shaped carbon nanoparticles and a method for producing an aluminum-carbon composite material using the same, in particular to a method for manufacturing plate-shaped carbon nanoparticles composed of a single layer or even tens of carbon atomic layers and its utilization. The manufacturing method of the aluminum-carbon composite material of the method. Background technique [0002] Carbon materials are materials with carbon atoms as the main component. They have been widely distributed in nature since ancient times, and have been used by people in the form of charcoal or ink long ago. In particular, carbon materials have physical properties such as ultra-high temperature resistance, ultra-light weight, and ultra-wear resistance, so they are widely used in cutting-edge materials recently, and become four major materials along with metals, ceramics, and polymers. [0003] In addition to th...
